The sexual act of a female gently squating flat-footed over the face of a man while he lies on his back. The female then rubs her vagina, 'taint' and anus across the man's mouth and nose. This can be done in repeated singular strokes or continuously while remaining in contact with the individuals face. Not to be confused with plain ol' face-sitting: this way the female controls various movements and intensity.

dude 1: "Last night my girl said she'd do anything I wanted."

dude 2: "So did you finally ask her to sit on your face?"

dude 1: "Naw man, even better. I asked her to give me a cherry strudel...and she did!"
